Solar application on Android
The past couple of weeks I’ve been working on an Android application to look at the solar panel production. The following screenshots show what this has lead to. The left picture shows the start-up screen, with a photograph of the actual panels and six buttons for each of the screens. The middle picture shows the […]
A sunny day with three clouds
The 19th of December 2011 was a good day for solar panels. The production that day was about 3.5 kWh and you can clearly see that the inverter got enough power to awake at around 9:00, being at peak around noon and going back to sleep at around 15:00. This looks hopeful for the summer, […]
Solar panel graphs
The last couple of weeks I’ve been running monitoring software that is connected to the Aurora inverter and receives measurements from it. The setup is as follows: A lot of measurements are available, such as voltage, current and power of both inputs (solar panel strings) and the grid, temperature of the inverter and its booster, […]
Solar inverter readout
I hooked up the Aurora Uno PVI-2000 solar inverter to a laptop with an RS-232 serial cable. Note that we need an RS-232 cable with a male connector on one end and a female connector on the other end. It also needs to be a straight connection, i.e. no cross between RX and TX. If […]
Solar panel installation
On Wednesday the 16th of November 2011 we installed some solar panels on our roof. The panels are from Trina Solar. Each panel produces 235 Watt peak (Wp), which means that the panels produce at most 235 Watt at any moment in time. If the light conditions are less favorable, the production will be less. […]
